Utica-Dunkirk 14662087 Compression Fitting

The Utica-Dunkirk 14662087 is a precision-engineered 1/8" OD compression fitting designed for high-reliability connections in hydronic heating and gas-fired boiler systems. As an OEM replacement part, this fitting ensures a leak-proof mechanical seal without the need for soldering, making it an essential component for technicians working in confined spaces or fire-sensitive environments. The 1/8 inch compression connection is specifically utilized for small-diameter tubing, such as pilot lines, pressure switches, or instrumentation ports where maintaining an airtight and fluid-tight interface is critical for system safety and combustion efficiency.

Constructed from durable brass, this HVAC compression fitting is built to withstand the thermal cycling and pressure fluctuations typical of Utica and Dunkirk boiler assemblies. The three-piece design includes a body, nut, and ferrule, allowing for a demountable joint that simplifies future maintenance. Integrating this Utica-Dunkirk boiler part into your service routine ensures field compatibility and original equipment performance, reducing the risk of call-backs caused by inferior universal fittings. When securing pilot tubing or sensing lines, this component provides the high-tolerance fit required for professional HVACR installations.

• Flame-Free Assembly: Eliminates the need for torches, reducing fire hazards in residential and commercial boiler rooms.
• OEM Compatibility: Exact replacement for Utica-Dunkirk part number 14662087, ensuring correct thread pitch and ferrule seating.
• Corrosion Resistance: Heavy-duty brass construction prevents degradation in high-moisture hydronic environments.
• Serviceability: Mechanical compression allows for easy disconnection and reconnection during component troubleshooting or cleaning.

Is this fitting compatible with plastic or copper tubing?
This fitting is designed for 1/8" Outside Diameter tubing and works effectively with copper, aluminum, and certain rigid plastic lines common in furnace and boiler instrumentation.

Does the sleeve/ferrule come included with the part?
Yes, this 1/8" OD compression fitting is typically supplied as a complete assembly including the nut and ferrule to ensure a proper mechanical bite on the tubing.

Can I use this for high-pressure refrigerant gas lines?
While designed for HVACR applications, this specific part is primarily used for pilot gas and low-pressure sensing lines in heating equipment. Always check your system's maximum operating pressure against the fitting's specification.
